Description

METHODS AND SYSTEMS FOR REDUCING CARBON
DIOXIDE IN COMBUSTION FLUE GASES
This invention relates generally to industrial combustion systems, and more particularly to methods and systems for removing carbon dioxide (C02) from combustion flue gases.
At least some known carbon separation technologies intervene at different points in coal and/or natural gas systems. For example, carbon separation technologies that separate CO2 from combustion flue gases are generally known as post-combustion carbon separation technologies. Known post-combustion carbon separation technologies include processes such as, but not limited to, physical absorption, cryogenic separation, solid sorbent separation, chemical looping combustion, chemical absorption, and/or membrane separation.
Some known chemical absorption processes attempt to remove CO2 from the flue gases by an exothermic reaction of CO2 with separation solvents, for example, potassium carbonate, sodium hydroxide, and amine-based solvents. Known amine-based liquids may include alkanol amines, for example, diethanolamine, triethanolamjne, activated methyl diethanolamine, and monoethanolamines (MEA).
During a known chemical absorption process, for example, a flue gas and an amine-based liquid such as MEA counter-currently flow within an absorber (scrubber). The flue gas may enter the scrubber near a bottom end, flow upward, and exit near an opposing top end. The liquid may enter the scrubber near the top end, flow downward, and exit near the bottom end.
A C02-rich liquid amine-based solution is formed by a chemical reaction of the flue gas and the MEA liquid in the scrubber. The C02-rich liquid is then channeled to a desorber (stripper). The stripper heats the C02-rich liquid to reverse the chemical reaction such that the absorbed CO2 is released from the liquid. The released CO2 may be subsequently compressed and transported to storage, and the C02-lean liquid may be recycled and reused in the scrubber.
The combustion flue gas stream generally includes a smaller volume of CO2 as compared to a larger volume of the flue gas. Known scrubbers generally require equipment sizes capable of processing the larger volumes of flue gas. During processing within known scrubbers, the flue gas is dispersed into the liquid causing gas bubbles to be formed within the liquid. The CO2 absorption amount of the liquid partially depends on a total gas-liquid contact area, which is the sum of the surface areas of the gas bubbles. The liquid may absorb CO2 and other impurities, for example, carbon oxysulfide and carbon bisulfide. Such known impurities may cause foaming of the liquid and/or liquid degradation due to irreversible reactions with the impurities. Also, a driving force that is required to separate the CO2 from the flue gas is determined based on a concentration (density) of flue gas components. The scrubber footprint and stripper regeneration energy increases capital cost, operating costs, and energy consumption. A plant capacity is also reduced because of electrical power consumption in known chemical absorption processes.
Some known membrane separation processes include porous membranes that allow selective permeation of gases. The CO2 absorption amount in the liquid partially depends on the physical interaction between flue gases and membrane materials, for example, polyimide and polyolefin. Membrane materials and pore sizes partially affect the degree in which one flue gas component permeates the pores as compared to other flue gas components. Compression of the flue gas is generally used to provide the driving force for permeation because a driving force that is used to separate the CO2 from the flue gas is a pressure differential across the membrane.
Therefore, a separation solvent and a stripper are not required for membrane CO2 separation as compared to known chemical absorption processes. Additional compression of the separated CO2 may be used for CO2 transport and/or storage.
Although known membrane separation processes generally use smaller scrubber sizes, such known scrubbers may produce a lesser amount of separated CO2 as compared to CO2 released using a chemical absorption process. As such, multiple recycling and processing of the flue gas may be needed in a smaller scrubber to achieve the same degree of CO2 separation as a larger scrubber that processes a similar amount of flue gas. The additional flue gas processing and compression further increase energy consumption and costs.
In one aspect according to the present invention, a method for processing flue-gas is provided. The method includes providing an absorber unit having a membrane contactor; channeling a combustion flue gas along a first surface of the membrane contactor; and channeling an ammonia-based liquid reagent along a second opposing surface of the membrane contactor. The method also includes partially separating the ammonia-based liquid from the flue gas such that the ammonia-based liquid and the flue gas contact at gas-liquid interface areas, defined by a plurality of pores of the membrane contactor, to separate CO2 from the flue gas by a chemical absorption of CO2 within the ammonia-based liquid to produce a C02-rich ammonia-based liquid.
In another aspect, a combustion system is provided that includes an absorber unit.
The absorber unit includes a housing for channeling a combustion flue gas; an ammonia-based liquid reagent channeled within the housing; and a membrane contactor coupled within the housing to separate the ammonia-based liquid from the flue gas. The membrane contactor includes a plurality of pores defining gas-liquid interface areas, with the ammonia-based liquid and the flue gas contacting at the gas-liquid interface areas to separate carbon dioxide from the flue gas by a chemical absorption of CO2 within the ammonia-based liquid to provide a C02-rich ammonia-based liquid. The combustion system also includes a desorber unit coupled to the absorber unit, so that the desorber unit receives and releases CO2 from the C02-rich ammonia-based liquid.
In another aspect, a flue-gas processing system is provided. The flue-gas processing system includes a housing for channeling a combustion flue gas; an ammonia-based liquid reagent channeled within the housing; and a membrane contactor coupled within the housing to separate the ammonia based liquid from the flue gas. The membrane contactor includes a plurality of pores defining gasIiquid interface areas.
The ammonia-based liquid and the flue gas contact at the gas-liquid interface areas to separate carbon dioxide from the flue gas by a chemical absorption of CO2 within the ammonia-based liquid to provide a C02-rich ammonia-based liquid.
Various aspects and embodiments of the present invention will now be described in connection with the accompanying drawings, in which: Figure 1 is a schematic diagram of an exemplary combustion system including a carbon dioxide scrubber; and Figure 2 is a schematic diagram of the exemplary CO2 scrubber shown in Figure 1.
The exemplary methods and systems described herein address certain disadvantages of known post-combustion carbon separation technologies by combining ammonia-based chemical absorption processes and hydrophobic membrane contactors.
Figure 1 is a schematic diagram of an exemplary combustion system 100 that includes a furnace/boiler 110, optional pollution control devices 120, a CO2 absorber (scrubber) 130, a preheater 140, a desorber (stripper) 150, and a steam generator 160.
Furnace/boiler 110 serves as a combustion chamber that includes fuel injection ports 112, air injection ports 114, and a combustion zone 116. In the exemplary embodiment, at least one fuel injection port 112 and at least one air injection port 114 are coupled to furnace/boiler 110 to inject fuel and air, respectively, into combustion zone 116.
After combustion of the fuel, a generated combustion exhaust gas, also known as a combustion flue gas, is optionally channeled in a transport stream into pollution control devices 120, for example, electrostatic precipitators, and/or filter baghouses, to undergo various environmental clean-up processes prior to CO2 separation within scrubber 130. The pollution control devices 120 may include environmental clean-up processes that facilitate removing impurities, for example, nitrogen oxides (NOr), sulfur oxides (SOs), fly-ash, oxygen, and/or other particulate matter present in the flue gas which may cause liquid absorption degradation.
Any remaining flue gas is then channeled to scrubber 130. Scrubber 130 processes the flue gas by using an ammonia-based liquid to facilitate separating CO2 from the flue gas (later described in more detail). After flue gas processing, the C02-free flue gas is optionally discharged to the ambient air, and the C02-rich ammonia-based liquid solution is channeled to preheater 140.
The C02-rich ammonia-based liquid is then channeled to stripper 150. Stripper 150 reduces pressure and/or increases temperature of the C02-rich liquid to facilitate releasing CO2 from the liquid. In the exemplary embodiment, steam generator 160 produces steam to reverse the chemical reaction by heating the C02-rich liquid to facilitate regenerating the CO2 from the liquid. The released CO2 is then compressed and/or dried for storage and/or transportation. The C02-free ammonia- based liquid is then recycled and channeled to scrubber 130 for subsequent flue gas processing.
Figure 2 is a schematic diagram of scrubber 130 (shown in Figure 1). In the exemplary embodiment, scrubber 130 operates to integrate membrane separation and ammonia-based chemical absorption technologies to capture CO2 from the flue gas.
Scrubber 130 includes gas-liquid membrane contactors 170 fabricated from hydrophobic material, for example, polytetrafluoroethylene (PTFE), including expanded polytetrafluoroethylene (ePTFE). Membrane contactors 170 each include a surface 172, an opposing surface 174, and micro-pores 178 that extend through contactor 170 and receive flue gas during processing. It should be appreciated that membrane contactors 170 may be fabricated as inert hollow fibers, substantially planar sheets, and/or other known structures packaged in a tube-and-shell arrangement, spiral-wound module, and/or other known configurations. Because membrane contactors 170 are densely packaged as hollow fiber and/or modular units -5.
in the exemplary embodiment, membrane contactors 170 provide a greater gas-liquid contact area per unit volume as compared to known scrubbers implementing only chemical absorption processes. As such, a smaller footprint of scrubber 130 can be customized and/or retrofitted to known industrial combustion systems. Also, PTFE membrane contactors 170 increase the surface area contact between the gas and liquid streams, making absorption more efficient than traditional absorption column configurations.
In the exemplary embodiment, membrane contactors 170 facilitate non-selective flow of flue gas components 176 into micro-pores 178 defined therein as compared to known porous separation membranes that selectively facilitate passage of flue gas components. Because membrane contactors 170 are hydrophobic, membrane contactors 170 facilitate preventing convective liquid flow across membrane contactor 170. Based on such hydrophobic and micro-porous material characteristics, membrane contactors 170 facilitate contacting flue gas components 176 and an ammonia-based liquid without dispersion of one phase in another.
Because membrane contactor 170 acts as a gas permeable barrier between the gas and liquid phases, membrane contactors 170 do not actually separate CO2 from flue gas as compared to known porous separation membranes. Instead, ammonia-based liquid 182 provides the exemplary hybrid process CO2 separation selectivity. In the exemplary embodiment, membrane contactors 170 act as contacting mediums between flue gas 176 and ammonia-based liquid 182 to facilitate CO2 separation from flue gas 176 based on a chemical absorption process. In other words, CO2 separation within scrubber 130 is determined by a reaction of flue gas 176 with the ammonia-based liquid separating agent within scrubber 130 as discussed in greater detail herein.
In the exemplary embodiment, the contact area between flue gas 176 and ammonia-based liquid 182 is an area sum of all gas-liquid interfaces 180 of all membrane contactors 1 70 provided within the scrubber. A packing density of membrane contactors 1 70 and/or micro- pores 178 provide a larger overall gas-liquid surface area contact as compared to total gas bubble surface areas caused by gas dispersion using known chemical absorption processes. As a result, membrane contactors 170 facilitate increasing CO2 absorption efficiency as compared to known chemical absorption processes.
In the exemplary embodiment, membrane contactor 170 is fabricated from hydrophobic materials such as PTFE. Particularly, membrane contactor is fabricated from expanded polytetrafluoroethylene (ePTFE). Expanded polytetrafluoroethylene has a surface area of about 10 to about 100 m2/gr and a void volume of about 90% to about 95%. The surface area and void content of expanded polytetrafluoroethylene permits flue 176 gas to contact ammonia-based liquid 182.
The PTFE material is suitable for flue gas processing operations as discussed with respect to the exemplary embodiment. For example, flue gas 176 generally has negligible amounts of hydrocarbon and large amounts of CO2. Also, in flue gas processing operations within scrubber 130, flue gas 176 is generally processed at about 50 C to about 100 C, in another embodiment, about 50 C to about 80 C, and all subranges therebetween. Because CO2 from flue gas 176 is absorbed by ammonia-based liquid 182 at ambient conditions, for example, about 50 C, pre-heating CO2 and/or ammonia-based liquid 182 is not needed as compared to known systems known systems that attempt to separate CO2 from flue gas using other liquid separating agents. As a result, ammonia-based liquid 182 facilitates reducing operating cost associated with CO2 absorption using other liquid separating agents.
Because PTFE is generally inert to flue gas components, membrane contactor 170 is fabricated from PTFE and/or other similar materials that are inert to flue gas 176. As a result of PTFE material, membrane contactor 170 does not swell under flue gas processing operations as compared to known off-shore oil drilling and/or sweetening operations. Also, PTFE facilitates controlling sizes of micro-pores 178 to control gas-liquid contact areas for increasing CO2 absorption efficiency.
In the exemplary embodiment, ammonia-based liquid 182 also facilitates increasing CO2 absorption efficiency as compared to known chemical absorption processes.
Ammonia-based liquid 182 has higher reaction energies and absorption capabilities as compared to other types of known liquid separating agents such as amine-based liquids. As a result of using ammonia as a liquid separating agent, ammonia-based liquid 182 facilitates reducing an amount of liquid that is capable of absorbing approximately equal amounts of CO2 as compared to other types of known liquid separating agents such as amine-based liquids. Because less ammonia-based liquid 182 is required for CO2 absorption, less heat/steam is required to regenerate CO2 from ammonia-based liquid 182 as compared to known systems that attempt to regenerate CO2 from other liquid separating agents. As such, a reduction in cost associated with regeneration is facilitated.
During flue gas processing in the exemplary embodiment, flue gas 176 and ammonia-based liquid 182 are channeled on opposite sides of membrane contactor 170 provided within scrubber 130. Although flue gas 176 and ammonia-based liquid 182 are illustrated as counter-current flows, it should be appreciated that flue gas 176 and ammonia-based liquid 182 may flow concurrently in a same direction. As describe above, mass CO2 transfer from flue gas 176 occurs by diffusion of CO2 through gas-liquid interfaces 180 using ammonia-based liquid 182 in a chemical absorption process as discussed in greater detail herein.
In the exemplary embodiment, a partial pressure gradient is applied within scrubber to transfer CO2 mass through diffusion from a gas phase to a liquid phase by lowering a pressure of the flue gas portion that is in contact with ammonia-based liquid 182. It should be appreciated that a vacuum, inert gas, and/or other driving force can create the necessary driving force for CO2 mass transfer. By controlling pressure differences between flue gas 176 and ammonia-based liquid 182, a portion of flue gas 1 76 is immobilized in micro-pores 178 of membrane contactor 170 so that each gas-liquid interface 180 is located at a mouth of each micro-pore 178.
Because membrane contactors 170 serve as partitions between flue gas 176 and ammonia-based liquid 182, a gas-liquid contact area is not disturbed by variations in flow rates. As a result of membrane contactor 170 and pressure control, scrubber 130 facilitates transferring flue gas 176 and ammonia-based liquid 182 over a wider range of independent flow rates as compared to flow rates of gas and liquids used in known scrubber systems. Membrane contactor 170 and pressure control also facilitate reducing flooding, channeling, and/or back-mixing of ammonia-based liquid 182 into micro-pores 178. As such, scrubber 130 can tolerate a wider range of variations in flue gas processing conditions as compared to known scrubber systems. Membrane contactors 170 also facilitate reducing foaming and/or solvent degradation by reducing dispersion of potential ammonia-degrading impurities in flue gas 176 in ammonia-based liquid 182. Because the driving force for CO2 separation from flue gas 176 is a pressure gradient, a density difference between gas and liquid components are not required. As a result, membrane contactors 170 require no selectivity to CO2 separation from flue gas 176 as compared to known porous separation membranes.
In the exemplary embodiment, scrubber 130 includes a hybrid of membrane contactor and ammonia-based liquid to facilitate CO2 separation from flue gas 176.
Because scrubber 130 includes membrane contactor 170, a gas-liquid surface contact area is increased as compared to known scrubber systems that attempt to separate CO2 only by known chemical absorption processes therein. As a result, membrane contactors 170 may be densely packaged as bundles and/or modules to facilitate reducing a scrubber size as compared to known scrubber systems. Because membrane contactor 170 is fabricated from a micro-porous hydrophobic material such as PTFE, membrane contactor 170 acts as an inert material barrier in flue gas processing.
Because ammonia-based liquid 182 is used as a liquid separating agent, the amount of liquid for chemical absorption of a given amount of CO2 is less than an amount required for other liquid separating agents. As a result, use of ammonia facilitates reducing a scrubber size as compared to a size of known scrubber systems. Also, use of ammonia-based liquid 182 facilitates reducing an amount of regeneration energy used to release CO2 in stripper 150 as compared to regeneration of CO2 from other liquid separating agents. Overall, scrubber 130 facilitates reducing equipment size and/or capital costs associated with flue gas processing to separate, absorb, and release CO2 to reduce such emissions.
Exemplary embodiments of scrubbers are described in detail above. The scrubbers are not limited to use with the specified combustion systems described herein, but rather, the combustors can be utilized independently and separately from other combustion system components described herein. Although the exemplary methods and systems are described above with respect to coal or natural gas plants, it should be appreciated that the exemplary scrubber systems and methods are also applicable to other combustion systems such as, but not limited to, combustion engines. Moreover, the invention is not limited to the embodiments of the combustors described in detail above. Rather, other variations of scrubber embodiments may be utilized within the spirit and scope of the claims.
While the invention has been described in terms of various specific embodiments, those skilled in the art will recognize that the invention can be practiced with modification within the spirit and scope of the claims.
